Specification of Letters Patent.

Patented July '7, 1914.

Application filed May 19, 1911. Serial No. 628,149.

To all whomz't may concern:

Be it known that l, CHARLES H. VVoRsEY, a citizen of the United States,residing at Pittsburgh, in the county of Allegheny, State ofPennsylvania, have invented a certain new and useful Improvement inCandy- Spinners, of which the following is a specification, referencebeing had therein to the accompanying drawings.

The invention consists in a rotary batchreducer or spinner of novelconstruction, for use in reducing and extending candy and other plasticand ductile material, and especially useful in the manufacture ofstickcandy.

The invention comprises various improvements which are hereinafterparticularly de scribed and claimed.

An embodiment of the invention is illustrated in the drawings, in whichlatter,-

Figure 1 is a view in end elevation of a spinner constructed-inaccordance with the invention, looking from the right hand side in Fig.2. Fig; 2 is a side elevation thereof with certain small portions ofstand 7 and boss 6 broken away. Fig. 3 is a detail View in section ofone of the cones and its supporting bearing. i

The spinner shown in the drawings consists, essentially, of a group ornest of cones 4, 4, etC., a rotatable carrier 5 therefor, and means forrotating the carrier so as to cause the group or nest to revolve aroundthe axis of the carrier, and for rotating the respective cones upontheir individual axes as they are thus revolved with the carrier. Thecones of such group or nest are disposed in a series which is concentricwith the axis of the carrier, and which incloses a central space orpassage for the reception of the batch of candy to be reduced. They areset close together in the said series, with their axes converging, sothat the central space or passage tapers gradually from the entrancethereof at the large ends of the cones toward the exit at the small endsof the cones. The respective axes of the individual coneshave a slighttransverse inclination or obliquity with relation to the prolongation ofthe axis of the carrier, so that the said axes cross the said axis atthe small ends of the cones without, however, intersecting said axis.

In operation, the batch of candy to be reduced is passed into thecentral space at the largeend' of the latter until it is engaged withthe surfaces of the cones. The directlon of the rotation of therespective cones upon their individual axes is the same as that in whichthe carrier and series of cones are revolved. Consequently the conesroll around in contact with the exterior of the batch. At the same time,because of the obliquity of their individual axes with reference to theaxis of rotation of the carrier, the rotation of the respective conesabout their said individual axes acts to impel or feed the batch towardthe small ends of the cones. The rolling action, taking placeconcurrently with the endwise feed of the batch, operates to reduce thebatch gradually in diameter until it has assumed the size of the exit atthe 'small ends of the cones and passes therethrough.

Certainof the special features of my invention comprise means forsupporting and driving the cones of a rotary spinner wholly from thelarge ends thereof, adjacentthe entrance to the central space that isinclosed by the comes, the small ends of the cones being free, clear,and readily accessible. The said features comprise, also, an extendedbearing-support for each cone. 1 These various features areshown inthedrawings. In the embodiment thereof that is shown in the latter thecarrier 5 is made, for convenience, as a disk or wheel having a hub orshort sleeve 5 and a central eye or opening. It is mounted upon abearing-support that consists of a long tubular boss 6 projecting from afixed stand 7, the said stand having an opening 8 therethrough, (shownin Fig. 2) which registers with the central opening or passage 6 throughthe boss. The open.- ing 8 of the stand 7, and the opening or passage 6withinthe bearing-support 6, are in line with the central space inclosedby the nest of cones, and the batch of candy passes therethrough toenter into the said central space; The tubular boss6 constitutes a guidefor the batch as the latter enters the spinner. Being stationary ornon-rotative such guide has no tendency to turn or twist the batch. If arotating guide were employed at this point in themachine, the contact ofits inner surface with the batch would tend to turn and twist thelatter. The cones 4L, 4, etc., are located entirely at the delivery sideof the disk-portion of carrier 5, their large ends being adjacent thesaid disk-portion. Forthe support of each cone upon the carrier Iemploy, by preference, and as one of the said spe'cialfeatures of theinvention, a long sleeve-bearing and a long pintle fitting together, onethereof being provided in connection with the carrier and the other withthe cone.

In the preferred construction, the cone is hollow from its large end fora considerable portion of its length, and the bearing is extendedlengthwise into the cone a considerable distance so that it serves tosupport the cone for a large portion of the length of the latter againstspringing under strain acting thereon at and adjacent its tip. In theillustrated embodiment of this portion of the in- 'vention, thesleeve-bearing is provided at 9 in connection with the carrier-disk, andthe pintle 10 is secured to the cone and fits and turns within the saidsleeve-bearing, although I consider that a reversal of this arrangementwould still be within the scope of the invention. By employing a longsleevebearing with considerable length of contact between thebearing-surfaces of the same and the pintle, the latter is sustainedagainst tendency to spring and bind in the bearing, and the rate of wearis reduced. The driving of the respective cones is affected in the saidembodiment by means ofpinions 11, 11, etc., fixed upon the portions ofthe pintles 1O, 10, etc., which project'through the sleevebearings 9, 9,etc. and a centrally-located bevel gear-wheel 12 with which the saidpinions. engage, the said bevel gear-wheel being formed upon a hub 12which is sleeved upon tubular boss 6 alongside hub 5 of carrier 5.*

In operation, rotary motion is communicated to bevel gearswheel 1'2 andto carrier 5, in the same direction but at different speeds, thegear-wheel being driven more slowly than the carrier, the result beingthat the rotation of the carrier revolves the series of cones around theaxis of the carrier and the gear-wheel 12 acts' through its engagementwith 'pinions 11, 11, etc., to cause the respective cones to rotate atthe proper relative rate of speed in the same direction upon theirindividual .axes. The carrier 5 and bevel gear-wheel 12 are driven atthe proper speed relative to each other by'means of suitable gearingfrom an actuating shaft,

, marked"l3. The said gearing comprises a spur-pinion 14 'fixedon' thesald shaft 13, a spur-gear 15 fixed upon or formed integral with the hub12 of the said bevel gearwheel, 'a spur-gear 16, with which gearwheel 15is in mesh, fixed upon a short sideshaft 17 supported in bearings instandards 18, one of which is shown in Fig. 1, and a second spur-gear 19fixed on the said short shaft 17 and meshing with spur-teeth formed onthe periphery of the carrier 5.

One aim in connection with the rotary spinner is to causethe conesthereof to revolve around the inclosed portion of the by so disposingthe said cones that the inclosed space shall be of proper proportions tojust receive another cone of the same size,

etc., and by so proportioning the-gearing that a revolution of a conewith the carrier and a rotation of the cone upon 1ts individual axisshall be performed in equal time.

By thus propo-rtioning the inclosed space so that the formed massofcandy occupying the same shall just correspond in shape and size withone of the conesof the spinner, and proportioning the gearing so thateach out-' side cone shall rotatejust once on its own axis in-revo-lvingonce around the candy, the respective cones will simply roll around thecandy without tendency to rotate or twist the candy itself. The sameresult may be attained in cases in which the inclosed space differs insize from the cones of the spinner, by proportioning the gearing so thatthe surface speed of a cone in rotating upon its individual axis shalljust equal the speed at which the cone is caused totravel around uponthe exterior of a conical mass of candy occupying the said space.

For working hard candy, as in the manufactureof stick candy, conesareemployed having smooth "surfaces, to thereby avoid any tendencytoroughen the surface of the candy, and to avoid feeding the candy alongtoo fast. For working upon soft candy, as in the manufacture of molasseskisses and the like, the cones will have longitudinally-grooved surfacesor the said surfaces will be otherwise adapted to take hold of thecandy. v v v In the special constructionlof cone shown in Fig. 3, thebody of the cone is bored longitudinally to receive the stem of thepintle 10. To engage the said body with the said pintle so as to preventit from turning relative thereto, and compel it to rotate in unisontherewith, the portion of the pintle which projects beyondv the forwardend of the sleeve-bearing 9 is made tapering, and the bore in the bodyof the cone is made correspondingly tapering to fit the said portion ofthe pintle. The cone is'forced tightly upon the pintle, into firmfrictional iio engagement therewith; The extremity of butt ends of thesaid cone-tips internallythreaded holes which fit' portions of thescrew-threaded extremities of pintles 10, 10, etc., that project beyondthe ends of the body-portions of the cones. The butt end of each tip isformed with a recess partly receiving the nut 22 on the correspondingpintle. One set of tips may be unscrewed from the cones and another setscrewed on in the place thereof. By providing sets of tips of differentlength and size, the diameter of the exit-opening at the small ends ofthe cones may be Varied, with corresponding variation in the diameter ofthe batch as it issues from the spinner.

I claim as my invention 1. In a candy-making machine, in combination, anest of cones around a coneshaped space through which the batch is fed,a carrier for said cones supporting the latter by one end only, theother end being unsupported and free, a central bearingsupport for saidcarrier constituting a nonrotating guide through which the batch entersthe said space, pinions in connection with the respective cones, a wheelturning on said central support and in driving engagement with saidpinions, and means for rotating the carrier and the said wheelrespectively.

2. In a candy-making machine, a rotary batch-spinner comprising a nestof reducing and feeding cones, and a carrier for said cones locatedwholly at the large ends thereof, leaving the other ends thereof freeand unsupported, said carrier having for each cone an elongatedsleeve-bearing extending within the cone for a portion of the length ofthe latter.

3. In a candy-making machine, a rotary batch-spinner comprising a nestof cones, a carrier for said cones located wholly at the large endsthereof, leaving the other ends thereof free and unsupported, and anelongated sleeve-and-pintle bearing-support for each cone, having oneelement thereof combined with the carrier and the other element thereofcombined with the cone, the said bearing-support extending within thecone a portion of the length of the latter.

In testimony whereof I aifix my signature in presence of two witnesses.
